Eucommia ulmoides is a valuable Chinese herbal medicine, which has the functions of supplementing liver and kidney, strengthening bones and muscles, benefiting waist and knees, and removing pain, and can also remove urine, urine and urine, and has a certain effect on hypertension. First, nursery 1, nursery choice: use loose soil fertile wet and well-drained land. 2. Prepare the bed for soil preparation: Before the nursery is carried out, plowing the plowing field deeply, remove the weeds, and apply enough basic fertilizer. Apply 150-200 kg of cake fertilizer per mu. At the same time, 10-15 kilograms of lime are applied per acre to disinfect the soil and kill the underground pests. Then the ground is trimmed to create a one-meter-wide seedling. 3. Seed treatment: After immersing the seeds in cold water for 30 to 40 days before sowing, the seeds that sink to the bottom of the water are 8 hours old; after soaking for 24 hours, the sinking seeds are medium; the rest floats on the water and floats The seeds in the water are inferior. The floating seeds were filtered out, and the sinking seeds were mixed with sand in a ratio of 1:3 and spread on a cool, ventilated surface for germination. After 30 days of storage, the seed was fully inflated and germinated, and the young shoots were slightly exposed to the white tip, ie, the sand grains were sowed to the nursery. 4, sowing technology: generally in the middle of March to March the average temperature is stable above 10 °C sowing, the use of drilling method, the pitch from 20 to 25 cm, sowing 7 to 10 kg per mu. The sowing depth is about 5 centimeters and the covering soil is 1 to 2 centimeters. After the soil is covered, the mulching bed or rice straw (or wheat straw) shall be placed on the seedbed to prevent the evaporation of the soil moisture and the impact of rain on the garden. Second, seedling afforestation, afforestation site selection: Eucommia afforestation best choice for sheltering sunny slopes, the foot of the mountain, the lower part of the mountain and the mesa platform soil deep, loose, fertile, well-drained acidic and slightly alkaline soil. Limestone exposed rocky crevices can be planted as long as the soil is deep. 2. Site preparation: The eucommia afforestation area must be as deep as possible and fully site preparation. In the afforestation area, a terrace with a width of 2m or more is made, and then a hole is made in the terrace. The hole is a square point 80cm wide (60cm deep), and the base fertilizer is cast in the hole. 3. Afforestation density: Generally, the row spacing is 1.52 meters, 22 meters or 23 meters, and the production practices of 111 to 222 per mu have proved that the 22-meter row spacing is the best. 4, planting techniques: seedlings before planting roots should be stained with mud, seedlings to stand in the center of the hole, a hand to help the seedlings, shoveling soil, and then gently raise the seedlings to make the seedling roots stretch. The depth of planting is slightly deeper than that of the original seedlings of the seedlings. Do not over depth, backfill the topsoil with layers, ply the layers firmly, and cover with a layer of loose soil. Third, the young forest tending 1. Remove the lower lateral buds: After the eucommia ulmoides plants are planted, remove the lower lateral buds of the stem stem as soon as possible, leaving only the top one or two robust and full lateral buds. Within the third month after the trees germinate, too many lateral branches should be cut off, and only 6 to 8 lateral branches should be kept as the best. 2, loose soil weeding: 2 times a year weeding soil. The first loose soil weeding time should be carried out before the beginning of April, the second time should be carried out in early June. It can also be used in combination with deep-turning land to intercropping forestry and farming. 3. Top dressing: The amount of fertilizer per acre is 8 to 12 kg of nitrogen fertilizer, 8 to 12 kg of phosphate fertilizer, 4 to 6 kg of potash fertilizer, or 25 kg of farmyard manure per plant, 15 to 18 cm of circular ditch, and soil covering after fertilization. 4, pruning in addition to pupae: the root of Eucommia, sprouting ability, so always on the ground sprouting litchi and side branches timely pruning to promote trunk growth.
